DETAILED DESCRIPTION

[0047] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inside", "outside", "front", "back", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] As a specific embodiment of the present invention, Figure 1-Figure 5 As shown, this embodiment provides an air outlet structure 100, which is mainly used in an air handling device 200. The air outlet structure 100 may include an inner air guide 110, an outer air guide 120, a first shell 130 and an air outlet 140. Among them, the outer air guide 120 and the inner air guide 110 together define an air duct 150. The first shell 130 is generally an arc surface, and the surface of the first shell 130 can be a combination of an arc surface and a plane, or all arc surfaces. Preferably, all surfaces of the first shell 130 of this embodiment are arc surfaces. The air outlet 140 may include an annular air outlet 141, and the air outlet is arranged downstream of the air duct 150 so that the gas in the air duct 150 is blown out by the air outlet 141. The air outlet 141 surrounds the outer periphery of the first shell 130. A curved surface 142 is further provided on the inner side of the air outlet 141 of the air outlet member 140, and the inner periphery of the curved surface 142 is connected to the outer periphery of the first housing 130. The curvature of the curved surface 142 is opposite to the curvature of the surface of the first housing 130, and the curved surface 142 extends inward from the air outlet 141 in a direction that is at an obtuse angle to the air outlet direction, so as to prevent the air blown out from the air outlet 141 from converging inward along the surface of the first housing 130.

[0049] Specifically, the air outlet structure 100 of this embodiment may include an inner air guide 110, an outer air guide 120, a first shell 130 and an air outlet 140. The inner air guide 110 and the outer air guide 120 define an air duct 150. The cross section of the air duct 150 may be annular. The wind in the air duct 150 is blown out by an air outlet 141 of the air outlet 140. The air outlet 141 of the air outlet 140 may also be annular. Preferably, the air outlet 141 is annular. The surface of the first shell 130 is generally arc-shaped. If the first shell 130 is directly arranged on the side of the air outlet 141, the wind from the air outlet 141 will converge inward along the surface of the first shell 130 (due to the Coanda effect). In this embodiment, a curved surface 142 is set between the first shell 130 and the air outlet 141. The curvature of the curved surface 142 is opposite to the curvature of the surface of the first shell 130, and the extension direction of the curved surface 142 is at an obtuse angle to the air outlet direction of the air outlet 141. The curved surface 142 is used to destroy the phenomenon that the air outlet 141 converges to the inside of the first shell 130, so that the air outlet 141 of this embodiment is not affected by the first shell 130, thereby avoiding the wind from the air outlet 141 converging to the inside of the surface of the first shell 130, increasing the air outlet area, accelerating the mixing speed of gases at different positions, and improving the user experience.

[0050] As a specific embodiment of the present invention, Figure 4 and Figure 5 As shown, there is a certain angle between the plane where the inlet position of the air duct 150 of this embodiment is located and the plane where the outlet position is located, so that the air inlet direction a and the air outlet direction b in the air duct 150 have an angle.

[0051] Specifically, the inlet and outlet of the air duct 150 of the present embodiment have a certain angle (i.e., not parallel), so that the air inlet direction a and the air outlet direction b have a certain angle (i.e., not parallel), so that the air outlet structure 100 of the present embodiment can be set to be inclined, and then by rotating the air outlet structure 100, the air outlet coverage area is made larger, making air purification easier and more uniform, further improving the user experience.

[0052] As a specific embodiment of the utility model, a blocking portion is provided between the inner air guide 110 and the outer air guide 120, and the blocking portion can divide the air duct 150 into a plurality of sub-air ducts. Specifically, the air duct 150 of the present embodiment is divided into a plurality of sub-air ducts, which can increase the flow rate of the gas, that is, increase the speed of the air outlet, and can also design the position of the sub-air duct according to the actual situation, thereby adjusting the air outlet position.

[0053] Specifically, Figure 6 and Figure 7As shown, the outer side wall of the inner air guide 110 of the present embodiment is formed with a first blocking portion 111 and a second blocking portion 112 which are arranged opposite to each other, and the outer sides of the first blocking portion 111 and the second blocking portion 112 are in contact with the inner side wall of the outer air guide 120 so that the air duct 150 is divided into two sub-air ducts. The two sub-air ducts can be distributed up and down or left and right. The sub-air ducts in the present embodiment are distributed left and right. Specifically, the first blocking portion 111 and the second blocking portion 112 of the present embodiment can divide the air duct 150 on the one hand, which can reduce the area of ​​the air outlet 141 and increase the flow rate of the gas at the air outlet 141, and on the other hand, it can also allow the inner air guide 110 and the outer air guide 120 to contact and position each other to avoid deformation or position movement.

[0054] More specifically, when the plane where the inlet of the air duct 150 of this embodiment is located is horizontal, the plane where the outlet of the air duct 150 is located is inclined (eg, Figure 1 , Figure 2 , Figure 4 and Figure 5 The first blocking portion 111 is located above the inner air guide 110, and the second blocking portion 112 is located below the inner air guide 110. The air duct 150 is divided into two left and right sub-air ducts by the first blocking portion 111 and the second blocking portion 112.

[0055] Specifically, the inlet of the air duct 150 of this embodiment is horizontal, and the air inlet direction a is a vertical direction. Since there is a certain angle between the air outlet direction b and the air inlet direction a, the air outlet 141 of this embodiment is inclined.

[0056] More specifically, the first blocking portion 111 and the second blocking portion 112 of this embodiment are respectively arranged above and below the inner air guide 110, so that the air duct 150 is formed into two left and right sub-air ducts, and the air outlet 141 is also formed into two left and right air outlets. In this way, the wind can be blown out from the left and right sides to form a ring-shaped wind.

[0057] As a specific embodiment of the present invention, Figure 6 and Figure 7 As shown, the first blocking portion 111 of this embodiment may include two first guide surfaces 1111 , both of which are planes, and the bottoms of the two first guide surfaces 1111 are connected and gradually extend apart upward at a certain angle.

[0058] Specifically, the first blocking portion 111 of the present embodiment begins to intersect at the middle and lower section of the first guide surface 1111 and extends all the way to the gas outlet. The two first guide surfaces 1111 are directly integrated with the inner air guide 110. And the outer sides of the two first guide surfaces 1111 are formed with side surfaces to connect the outer sides of the two first guide surfaces 1111. The two first guide surfaces 1111 of the present embodiment are gradually separated upward from the bottom at a certain angle, and they basically guide along the gas flow direction, so that the gas flows along the air outlets on both sides.

[0059] As a specific embodiment of the present invention, Figure 6 and Figure 7 As shown, the second blocking portion 112 of this embodiment may include two second guide surfaces 1121, both of which are curved surfaces. The bottoms of the two second guide surfaces 1121 are connected, and gradually separate upward at a certain angle and bend towards each other.

[0060] Specifically, the structure of the second blocking portion 112 of the present embodiment is substantially the same as that of the first blocking portion 111, except that the second guide surface 1121 of the second blocking portion 112 is a curved surface 142. The second blocking portion 112 is also gradually separated from the bottom to both sides and extends upward. The airflow can also flow along the second blocking portion 112 to the air outlets on both sides. Through the first blocking portion 111 and the second blocking portion 112, the gas in the air duct 150 can flow downstream to the two air outlets 141 and then be blown out, and the gas in the air duct 150 will not be turbulent, causing airflow disorder.

[0061] As a specific embodiment of the present invention, Figure 8-Figure 10 As shown, the air outlet structure 100 of this embodiment may also include at least one flow guide member 160. The flow guide member 160 may include a mounting portion 161 and a flow guide portion 162. The mounting portion 161 is connected to the inner air guide member 110 and the outer air guide member 120 and is connected to the air duct 150. The flow guide portion 162 is connected to the air outlet member 140. The gas in the air duct 150 passes through the mounting portion 161 and the flow guide portion 162 in sequence and is blown out from the air outlet 141 of the air outlet member 140.

[0062] Specifically, the air guide 160 of the present embodiment may include a mounting portion 161 and an air guide portion 162 . Since the air duct 150 of the present embodiment is divided into two, the air guide 160 of the present embodiment is also divided into two.

[0063] In this embodiment, the cross-sectional area of ​​the mounting portion 161 is greater than the cross-sectional area of ​​the air guide portion 162 , so that the flow velocity of the wind from the air duct 150 can be increased when passing through the mounting portion 161 to the air guide portion 162 .

[0064] The mounting portion 161 can not only be connected and mounted with the inner air guide member 110 and the outer air guide member 120 , but other components, such as a heating component, can also be mounted therein.

[0065] Specifically, the guide portion 162 of the present embodiment is further provided with a plurality of guide blades 1621 to limit the direction of the airflow blown out from the air outlet 141 .

[0066] Specifically, the air outlet 141 in this embodiment is designed to be inclined, so its air outlet direction is inclined upward. In this embodiment, the air outlet direction can be limited by the guide blades 1621, so that the air outlet direction can be changed according to the design. Specifically, the guide blades 1621 of this embodiment are all inclined downward along the ring shape, so that the wind blown out from the air outlet 141 is basically in the horizontal direction. When the air outlet 141 can be rotated, the range of the wind sweeping can be further expanded.

[0067] As a specific embodiment of the present invention, Figure 10-13 As shown, the air outlet structure 100 of this embodiment may further include at least one heating component 170 , and the heating component 170 is disposed at the mounting portion 161 , so that the wind blown out from the air duct 150 passes through the heating component 170 and then blown out from the air outlet 141 .

[0068] Specifically, the air outlet structure 100 of this embodiment may further include at least one heating component 170, so that the air blown out from the air outlet structure 100 may be hot air, thereby avoiding the indoor air being cooler due to the blowing of the air outlet structure 100 when used in winter, thereby affecting the user experience. In addition, since the air outlet structure 100 can blow hot air, the device used by the air outlet structure 100 (such as an air purifier, a fan, etc.) can be used as a heating device, thereby increasing the use range of the device.

[0069] As a specific embodiment of the present invention, each heating assembly 170 of this embodiment may include a plurality of heating modules 171 and a connecting member 172. Specifically, each heating module 171 of this embodiment may include at least one heating element 1711 and a first heat sink 1712 connected to both sides of the heating element 1711, the heating element 1711 extending along a straight line, and one side of each first heat sink 1712 connected to the heating element 1711 extending along a straight line. The connecting member 172 connects the plurality of heating modules 171 to each other to form a structure matching the cross section of the mounting portion 161.

[0070] Specifically, the heating module 171 of this embodiment may include a plurality of heating modules 171 and a connecting member 172, and the heating module 171 may include a heating element 1711 and a first heat sink 1712. Generally speaking, the heating element 1711 is a ceramic plate made of a PTC material. PTC is the abbreviation of Positive Temperature Coefficient. The PTC heating device is usually made of a PTC material, which has a special resistance-temperature characteristic, that is, within a certain temperature range, its resistance increases with the increase of temperature, and it can generate heat when powered on. The first heat sink 1712 can be arranged on the side of the heating element 1711, in contact with the heating element 1711, and dissipate the heat generated by the heating element 1711. The first heat sink 1712 can be a corrugated sheet or other heat dissipation structure, and can be made of materials with good thermal conductivity such as aluminum and copper.

[0071] More specifically, since the air outlet 141 in this embodiment is annular, the guide member 160 is also basically designed as an arc-shaped structure, and the heating assembly 170 is arranged at the mounting portion 161, so the heating assembly 170 also needs to be designed as an arc-shaped structure that matches the mounting portion 161. Since the heating element 1711 of this embodiment is a ceramic plate, it is generally a flat plate. If you want to form it into an arc-shaped structure, the prior art directly forms the first heat sink 1712 into an arc shape, and then contacts with a plurality of heat sinks 1711 that are interconnected and formed into a broken line, and finally forms an arc-shaped heating assembly. However, such a design results in poor contact between many first heat sinks 1712 and the contact surface of the heat sink 1711, resulting in poor heat dissipation and affecting the efficiency of heat dissipation. In this embodiment, the heating assembly 170 is formed by a plurality of heating modules 171 and a connector 172. Each heating module 171 can include at least one heat sink 1711 and a first heat sink 1712. Since the heating element 1711 extends in a straight line, the portion of the first heat sink 1712 that contacts the heating element 1711 also extends in a straight line, so the first heat sink 1712 and the heating element 1711 are in contact with each other, which will not affect the heat dissipation effect of the first heat sink 1712. In addition, since the cross section of the mounting portion 161 is an arc shape, in this embodiment, multiple heating modules 171 can be connected by a connector 172 to form a shape that matches the cross section of the mounting portion 161. For example, although each heating module 171 extends in a straight line, multiple heating modules 171 extending in a straight line are connected to each other to form a structure similar to or close to an arc, which not only satisfies the arc structure, but also ensures the heat dissipation effect.

[0072] As a specific embodiment of the present utility model, each first heat dissipation element 1712 of this embodiment is bent to form a structure with a bent cross-section. Each first heat dissipation element 1712 includes a plurality of first bending portions 1713 close to one side of the heat generating element 1711. The plurality of first bending portions 1713 are arranged side by side and extend along a straight line so that all the first bending portions 1713 are in contact with the heat generating element 1711.

[0073] Specifically, each first heat sink 1712 of the present embodiment is a bent structure, which is continuously bent to form a denser structure, thereby increasing the contact area between the first heat sink 1712 and the air, thereby increasing the heat dissipation performance of the first heat sink 1712 and improving the heating efficiency of the heating assembly 170. In addition, the plurality of first bent portions 1713 extend in a straight line, so that all of the first bent portions 1713 can contact the heating element 1711, further ensuring the heat dissipation effect and improving the heating efficiency.

[0074] As another specific embodiment of the utility model, each first heat sink 1712 of the present embodiment may further include a plurality of second bending portions 1714 away from one side of the heating element 1711. Each heating module 171 may further include a second heat sink 1715, one side of each second heat sink 1715 is connected to each second bending portion 1714 of the corresponding heating element 1711, and the other side of each second heat sink 1715 is connected to the connecting member 172.

[0075] Specifically, the second heat sink 1715 of this embodiment contacts each second bending portion 1714, thereby ensuring that all heat on the first heat sink 1712 can be transferred to the second heat sink 1715. The connecting member 172 can be connected to the second heat sink 1715, and the second heat sink 1715 is formed into a structure matching the mounting portion 161. In this embodiment, the second heat sink 1715 can be a metal sheet, and the connecting member 172 can also be a metal sheet, both of which have a certain ductility. Therefore, the second heat sink 1715 and the connecting member 172 can be designed according to the extension direction and structure of the second bending portion 1714 to ensure that the second heat sink 1715 is in full contact with the second bending portion 1714.

[0076] Preferably, a plurality of second bending portions 1714 may be arranged side by side along a straight line, so that the second heat sink 1715 is also formed with a straight cross section, and the connecting member 172 may be formed into a folded line, wherein the straight line segment contacts the second heat sink 1715 .

[0077] Specifically, in this embodiment, first heat sinks 1712 are disposed on both sides of the heating element 1711, so second heat sinks 1715 are disposed outside the first heat sink 1712 on each side, and connectors 172 are disposed outside each second heat sink 1715. Therefore, connectors 172 may include first connectors 1721 and second connectors 1722, and the first connectors 1721 and the second connectors 1722 respectively connect a plurality of second heat sinks 1715 located on the same side of the heating element 1711.

[0078] In some embodiments, Fig.11 and Fig.12 As shown, the first connector 1721 and the second connector 1722 can also be used as conductive components for transmitting current, and the heating element 1711 is electrically connected to the first connector 1721 and the second connector 1722 through the heat sink. The first electrode terminal 1723 can be provided on the first connector 1721, and the second electrode terminal 1724 can be provided on the second connector 1722. The first electrode terminal 1723 and the second electrode terminal 1724 can be connected to the circuit. When the circuit is turned on, the current is introduced into the heating element 1711 through the first electrode terminal 1723, the second electrode terminal 1724, the first connector 1721, the second connector 1722 and the heat sinks on both sides of the heating element, so that the heating element 1711 generates heat.

[0079] Specifically, Fig.13 As shown, the heating component 170 may further include a temperature control unit 173, which is used to control the temperature of the heating component 170. The temperature control unit 173 may be directly mounted on the first connecting member 1721 and the second connecting member 1722. Since the first connecting member 1721 or the second connecting member 1722 is a flat surface at the connection with the second heat sink 1715, the temperature control unit 173 can maintain assembly stability when it is arranged at this position. Compared with the assembly structure of the temperature control unit 173 that needs to be additionally arranged on a curved surface, the temperature control unit 173 is installed on a relatively flat surface in this embodiment without the need for additional assembly structures, thereby reducing accessories, reducing the overall volume, and improving the assembly efficiency and temperature control accuracy of the temperature control unit 173 to a certain extent.

[0080] Specifically, the heating assembly 170 of this embodiment may include a plurality of heating modules 171, and each heating module 171 may include a heating element 1711 and two first heat sinks 1712 located on both sides of the heating element 1711. The plurality of heating elements 1711 extend along the fold line. The first bending portion 1713 of each heating element 1711 contacts the heating element 1711, and the second bending portion 1714 of each heating element 1711 contacts the second heat sink 1715. The first connecting member 1721 connects the second heat sink 1715 located on one side of the heating element 1711, and the second connecting member 1722 connects the second heat sink 1715 located on the other side of the heating element 1711. The first connecting member 1721 and the second connecting member 1722 are parallel to the heating element 1711 at the connection position with the second heat sink 1715. The heating assembly 170 not only satisfies the requirement that it can be set at the arc-shaped mounting portion 161, but also ensures the efficiency of heating.
